4.6 Operation and maintenance specifications for main accessories of gas
engines
4.6.1 Operation and maintenance of turbocharger
The engine oil of turbocharger is drained from the main oil line of engine, and returns to the
bottom of crankcase after lubricating and cooling the turbocharger are complete.
（ 1 ） A good lubrication is crucial to the normal operation of turbocharger. Therefore, the engine

The turbocharger works at an extremely high rotating speed. Therefore, the engine shall run
idle (for about 5 minutes; the duration may be shortened as appropriate in case of a short-term
shutdown) before it is loaded. Do not shut down the engine immediately when it is running at a
high speed under a heavy load. The load and rotating speed shall be lowered gradually and the
engine shall idle for 3 to 5 minutes; otherwise the turbocharger bearing will be damaged and
become unusable.

4.6.2 Operation and maintenance of water pump
M26 series engine pump installed in the front of the engine, the pump turbine housing above the
timing gear chamber, cast into one, the turbine shell water directly into the right side of the water
chamber, cooling water across the oil cooler, from the lower right channel hole Into the cylinder
tube water sandwich, cooling cylinder tube and then through the water hole into the cylinder head
water chamber, after cooling the cylinder head from the cylinder head outlet into the outlet pipe,
outlet pipe end thermostat. Thermostat has two outlets, all the way to the tank, the other way to
the pump inlet is a small cycle. When the cooling water temperature in the thermostat open to
fully open temperature, then all the cooling water after cooling by the radiator into the body by
the pump, but when the cooling water is lower than the opening temperature, the thermostat cut
off the access, Cooling water directly into the pump inlet, so that the engine heat up as soon as
